First it was for moving map EFIS - OK - had a small hockey puck blu-tooth GPS receiver - worked great. Then ADSB comes along - need a WAAS GPS. Went the uAvionix SKYFYX-EXT/echoUAT route. Was actually able to get the GPS info off of the WIFI the echoUAT setup. Runs the adsb AND the Foreflight app running on the iPad. Sweet. This year I hope to finish the build on the Wittman Buttercup I have been building. Because of where I fly, it will have adsb plus a new 406Mhz ELT - which is supposed to have GPS position input! Im not familiar with RS232 usage (thats used between the uAvionix GPS receiver and the echoUAT) but it would be nice to share/use that data-stream instead of adding yet another GPS receiver. Is that possible? What about tapping into the WIFI GPS position data being generated by the echoUAT? I know, Im probably way out to lunch on this - but it seems there ought to be a better way. What say you?

(Except for the few ELTs that have internal GPS receivers.) In my plane, I just spliced into the RS-232 line running from the GPS to the transponder (GPS TX pin to the transponder RX pin). I ran that line to the ELT RX pin. As a computer guy, who always thought of RS-232 as bi-directional communication, this seemed weird. I had to wrap my head around the notion that RS-232 is being used to broadcast information (kind of like an FM radio station) so it works just fine to hook one device's TX pin to the RX pins on several devices. -- Art Z.

Check your ELT to make sure it will take NMEA protocol and 115200 baud input. Of course, the cheapest and easiest solution is not to have GPS position going to your ELT. Seems silly to have that capability and not use it but I've seen lots of installs done this way.

I'm amazed by how many owners with that unit don't bother to run two wires from their "portable" gps that sits on the panel and is plugged into aircraft panel anyway. Waiting several minutes for a 406 elt to attempt to acquire a position after activation is giving up a lot of the benefit of a 406 unit. Ken On 06/01/2020 1:06 PM, Sebastien wrote: > Wow.
